Application fi1ed-December 1 7, 1926., semim 155,539.

This invention relates. to improvements in heatingdevices, havingfen an ob ect to provide a device for heating the cooling medium'o i an internal combustion engine] during cold oririgid weatherto an'eX-tent or degree suflicient to prevent freezing"o-f the medium about the engine without: damage thereto or to those accessories employed in its cooling mediumci-rculating system.

It is also. an object of the inventionto provide a heating device of the character mentioned which can be installed upon, an internal combustion engine without alteration" or modifiizati-on of the same and which, when functioning, will be fire proof and thus, avoid burning of the engine or of the vehicle propeliled" thereby;

Yet another object of the invention: is: to provide-a burner for the. device, the same beinghoused within said device and bei-ng of a construction such as will eitect the production of an evenand uniform heating flame of maximum degree throughout its length with but a minimum fuel? consumption. j

Other objects; of the invention willbe in part obvious and in part pointedout hereinaiitcr.

In these. drawings: I l I Figure 1 is a fragmentary side elevation of an internal combustion engine having the water supply pipe of. the cooling-- me dium circulating: system thereof: equipped with the invention,

Figure 2 is. an enlarged side elevationof the improved: heating device;

Figure 6} is'a longitudinalsection through the housing ofthe heating device, taken on the line 6'6 of Figure 2; looking: in the direction in. which the: arrows point; and.

Figure 7 is a vertical longitudinal: section through the improved burner.

Having more particular reference to the drawings in connection with which "like characters of neference will designate conresponding parts throughout, the improved heating device may-be stated to: comprise a housing creasing of sheet 1 metal generally designated byi'the numeral: t, the bottom,

side and end walls of said housingbeing closed whereas: the top of the same is Open and the upper'portions on the opposite side walls. thereof are formed with outwardly extending-rightangu-larlly disposed flanges 2,. the intermediateapontion of one of which carries upon its under side a: block. or plate 31 formed with a screw threaded opening corresponding with a similar opening formed in the adjacent portions of the corresponding flange 2;: for a purpose which will-he subsequently described". r

The open top of the housing l is aidapted -t0a receive a;' cover plate 4 thereupon; said cover plate being ot a. length corresponding to the length of the housing I and ha ving a longitudinally disposed pocket fi 'fihrmed throughout the v same and adapted to be re ceived within the opposite side and: end

walls of the upper portion o f'the housing-in the manner shown inthe Figure 3, one side of said top plate being'hingedly connected to the adjacent" flange 25 as is: indicated by the numeral 6, thus permitting the swinging' 01f; the longitudinally depressed! pocket 5 from: without the open upper end of'the housing 1, whereby access-may he had? to the interior of! the same. That: the top plate: t may be secured in its closed postthe housing 1:, a lockingscrew is: passed through an intermediately' arranged open.- ing: in-the free side of said plate and this locking; screw is adapted to beturned into engagement with the screw threaded open.- ing formed in the plate 3, hereinbeilore described. Thus; itiwillrbe understood that the top tmay be secured in its closed posiz tion wi-th respect tothe open upper end: of the housing" 1, as may be -re'quiredt With; a view towardproviding the; devicetion: with respect to the openupper end of with. means for attaching or securing the samete the water supply pipe 8 of-thecool;

ing system offan internal combustion eni- I gine, 1': provide plnnality oii inetallhanger straps. 9; forming op'enings in the opposite extremities: thereof adapted to! be aligned with corresponding openings. in the opposite side: portions-'ot'the top platmet, whereupon securing bolts and; nuts amewpassedthrou-g h said opposite sides otthc topiiplatfl's k and the opposite" extremities: ofi'thee stumps 9. hence, effecting: a positive connecticn 0t the latter to the former. Before engaging the bolts and nuts 10 inthe manner described, it will be understood that .the lower portion of the water supply pipe 8 of the cooling medium circulating system of the equipped internal combustion engine is arranged in a longitudinally disposed and depressed pocket in said top plate 1, whereupon the hanger straps 9 are engaged over the upper portion of said pipe 8 in the manner shown in the Figure 1, following which. the bolts and nuts 10 are then engaged so as to effect. a supporting or attaching connection of the heating device to the underside of said pipe 8.

A longitudinally disposed fuel conveying pipe 11 is extended throughout the length of the bottom of the housing 1 and, as shown in the Figure 6, has the upper side thereof cut away as indicated at 12 while a plurality of equi-spaced openings or perforations 13 are formed in the bottom thereof, in order that the particular fuel en'iployed in connection witn the heater may be discharged into said bottom of the housing 1 and evenly distributed throughout its length for supply to the burner, hereinafter more fully described. The bottom portion of the housing 1, preferably, is provided with a layer of absorbent materiah'such as raw cotton or the like, designated by the numeral 14E, such material being arranged closely about the fuel supply pipe 11 and thus serving to receive and evenly absorb and distribute the inflow of fuel to the device, in order that its even distribution to the burner will be in sured.

Also, the upper portions of the opposite side Walls of the housing 1 are formed with a plurality of relatively spaced air admitting openings or ports generallydesignated by the numeral 15, whereas larger openings 16 are formed intermediately of the aforesaid opening and obviously serve to permit of ready ignition of the burner within the device when desired; likewise, to allow of inspection of the burner or the flame produced therealong.

The burner of my improved heating device may be stated to comprise a body portion constructed of sheet metal or other suitable material, correspoiuling to that from which the housing 1 is constructed, said body including opposite sides 17 formed with op positoly disposed supporting feet 18, while bands or cross pieces 19 span the opposite ends of the burner body and, obviously, serve to effect proper relative spacing of the opposite sides 17. The upper or top portion of the burner body is reduced by bending the upper portions of the opposite side walls 17 thereof inwardly as shown at 20 and then forming inturned flanges 21 upon the same, the intermediate portions of the inwardly disposed guards 20 of the burner being formed with series of equi-spaced openings generally indicated by the numeral. 22, whereby a proper supply of oxygen to the heating flame will be insured.

The upper portions of the side walls 1'? of the burner are maintained in rigid relative spaced relation by the insertion of transversely disposed bracing pins 28, the opposite ends of which are reduced and received in equi-spaced openings orperforations 2 1 formed in upper portions of said walls 17 below the aforesaid oxygen admitting openings 22. Thus, it will be understood that inward flexing or bending movementof the upper portions of the walls 17 or contraction of the same by reason of the application of high temperatures thereto will be prevented and consequently effectual functioning of the burner will at all times be insured. In this connection, it is to be noted that the length and width of the burner such as to permit of the snug reception within the heater casing 1, as is indicated in the Figure 3. I

The lower portion of the burner body is adapted to be supplied with a quantity of absorbent material, such as raw cotton or the like, designated the numeral 25, this packing or filling being extended upwardly between the side walls 17 to a point'immediately below the perforations 2 1-, whereupon the longitudinally disposed screen 26 is arranged over the same and beneath the cross pins 28, aforesaid, as is clearly shown in. the Figures 3 and 7. Another longitudinally disposed screen 27 is arranged in the upper portion of the burner body between the opposite side walls 17 thereof, the opposite sides of this particular screen being joined or fixedly connected to adjacent portions of the inwardly bent parts 20 of said walls 17, thus providing a chamber or pocket immediately above said screen 27 in which fibrous asbestos or similar matter 28 is packed, said matter 28 being arranged so as to lie substanti ally flush with the open upper surface of the flanged portions 21 of the reduced or inwardly disposed sides 20 and being held against displacement with respect thereto through the medium of a plurality Oii E'QlQtlYGlT/ spaced ties or wires 29., the opposite ends of which are bent upon themselves and en ged in adjacent openings 22. lly positioning or arrangement of the asbestos iibre 28 within the reduced upper portion of the burner body, it will be nude"- slood that a chamber will be effected be tween the upper portion of the absorbent ma tcrial and said asbestos fibre 28, whereby to insure the conversion of the liquid fuel employed in the heating device into a highly combustible gas having air admixed therewith in proper prop rtion for sustaining perfect combustion along throughout the length of theasbestos fibre 28.

To permit of placement or removal of the moagow burner in: onfrom the casing 1 of' the-heating device', a bale like handle 3O is-providcd;

thereof ands engagedin theadjacent perf01atiOI1S 22;&S' is shown in the Figures 4 and Thus, the handle 30'may be swung upwardly. so as to'pcrmit of dropping of tho'burner intothe casingl whereupon said handle maybe then swung dowmvardly over adjacent portions of the end. wall of said housing and the handle thus arranged without the. housing-and accessible; at. all times, as may be required;

The supply'pipe 11 maybe and: preferably is provided with a union or nipple 32 adapted to be connected to, a supply pipeor corresponding coupling upon a: suitable liquid fuel reservoir 33 arranged aha-n appropriate or convenient place upon the engine equipped vehicle. I

In operation of my improved heating device and assuming that the same is connected to the under side of the water return pipe 8 of thecooling medium circulating system in the manner hereinbefore described, fuel is discharged by way of the supply pipe 11 into the bottom of the casing 1 having the layer of absorbent material 14 therein. This fuel in turn is taken by capillary at traction upwardly to the absorbent material 25 throughout the entire length of the burner and during such passage is converted into a highly combustible gas, which in turn is delivered through the mesh of the screens 26 and 27 to the asbestos fibre 28 arranged flush with the open upper side of the reduced top portion of the burner 20, whereat the same is ignited and burned throughout the entire length of the burner, directing a heating flame onto the underside of the top plate 4 having the longitudinally dispose and depressed pocket 5 therein and in which the under side ofthe water supply pipe 8 of. the cooling medium circulating system isarranged. In this way. it will be understood that the water or other cooling medium passing through the water supply pipe 8 of the circulating system will be maintained at a temperature such as will prevent freezing, with the resultant damage of the engine or of those accessories employed in the. cir-' culating system. as well as bringing about material inconvenience to the operator of.

the engine equipped vehicle.

The heating flame produced by the burner may, of course, be regulated to the (lQSlIGCl nicety by suitable control of the supply of fuel to the supply pipe 11 through a valve or other suitable device (not shown) interposed in the fuel supply line.

By reason of the removable arrangement of the burner within the housing 1, it will be understood that the active parts of my.

improved. heating; device may-be readily: dis' assembledifon cleaning; repair ornO then punpose that maybe requ red and: hkewlse, by IGZISOIL of'this" convenient: arrangement of parts; the heating device may: installed upon am internal "combustion engine inr but aminimuin amount of time and by unskilled labor;
